Three Non-Profits Join Forces to Protect Skaneateles Lake Watershed

Coalition aims to combat harmful algal blooms and implement restoration projects to safeguard the watershed.

Skaneateles, NY

Harmful algal blooms (HABs) have become a significant water quality concern for the Finger Lakes region. They prevent people from swimming, fishing, and boating, and can cause entire shorelines to shut down, reducing tourism and public recreation. They can also threaten our drinking water supply. Skaneateles Lake, which serves as the unfiltered source of drinking water for over 200,000 households in neighboring municipalities and the City of Syracuse, experienced HAB outbreaks in September 2017 and again in August through October 2018. 

In response to these outbreaks, three local non-profits—The Nature Conservancy, Finger Lakes Land Trust, and

Skaneateles Lake Association—have come together to identify the main sources of HABs in the region, support local organizations working to address HABs, and help solve water quality problems in the watershed. 

By collaborating with the City of Syracuse, Cornell Cooperative Extension of Onondaga County, Onondaga County Soil and Water Conservation District, NYS Department of Environmental Conservation, Syracuse University, SUNY ESF, Finger Lakes Institute, and other groups the coalition hopes to protect the local watershed and improve quality of life for people in the region for decades to come.

HABs are occurring in the Finger Lakes in part because past land uses have caused a buildup of nutrients such as nitrogen and phosphorous at the bottom of lakes. Skaneateles Lake is classified as ‘oligotrophic’, as it has low productivity due to low levels of nutrients. This helps keep algae and other aquatic vegetation to a minimum and keeps the water clear. In fact, Skaneateles Lake was widely thought to be immune to HABs—until the first bloom occurred. A variety of causes including the changing climate, degraded tributaries and invasive species, are all thought to play a role. 

But nature can offer solutions; protecting and restoring lands and waters can help reduce the nutrients that cause blue-green algae blooms. That is why the coalition is collaborating on ongoing landowner engagement and outreach, remediation and restoration projects, and grant funding.

“SLA is thrilled to have Finger Lakes Land Trust and The Nature Conservancy working closely with us in the watershed,” said Rachael DeWitt, Skaneateles Lake Association Executive Director. “Each of us brings an area of expertise to the table, and as a result, we are stronger when we work together.”

“We couldn’t accomplish our conservation goals without the help of our partners,” said Andy Zepp, Executive Director of the Finger Lakes Land Trust. “We are excited to coordinate together on projects that help protect the watershed.”

“By working together, we can harness the power of nature to filter out nutrients before they reach our lakes, ensuring that local communities have access to clean water,” said Jim Howe, The Nature Conservancy’s Central and Western New York Chapter Director. “This collaboration will allow all of our organizations to do more, faster.”

The Nature Conservancy is a global conservation organization dedicated to conserving the lands and waters on which all life depends. Guided by science, we create innovative, on-the-ground solutions to our world's toughest challenges so that nature and people can thrive together. We are tackling climate change, conserving lands, waters and oceans at an unprecedented scale, providing food and water sustainably and helping make cities more sustainable.
